#Cognitive #leisure activity and all-cause mortality in older adults: a 4-year community-based cohort

Cognitive leisure activity, such as reading, playing mahjong or cards and computer use, is common among older adults in China. Previous studies suggest a negative correlation between cognitive leisure activity and cognitive impairment. However, the relationship between cognitive leisure activity and all-cause mortality has rarely been reported. ObjectivesThis study aims to explore the relationships between cognitive leisure activity and all-cause mortality in a community-based older … Continue reading #Cognitive #leisure activity and all-cause mortality in older adults: a 4-year community-based cohort

Associations between adolescent #cannabis use and young-adult functioning in three longitudinal twin studies

Observational studies have linked cannabis use to an array of negative outcomes, including psychiatric symptoms, cognitive impairment, and educational and occupational underachievement. These associations are particularly strong when cannabis use occurs in adolescence. Nevertheless, causality remains unclear. The purpose of the present study was thus to examine associations between prospectively assessed adolescent cannabis use and young-adult outcomes (psychiatric, cognitive, and socioeconomic) in three longitudinal studies … Continue reading Associations between adolescent #cannabis use and young-adult functioning in three longitudinal twin studies

The mixed benefits of a #stressor-free life.

Research documents the pernicious effects of daily stressors on well-being, but often ignored in these studies are people reporting no stressors. The current study compared adults who reported no daily stressors with adults who reported at least one stressor across 8 consecutive days on measures of well-being. Of the 2,804 respondents (age range = 25–75 years, M = 53.46) from the Midlife in the United … Continue reading The mixed benefits of a #stressor-free life.

Relationship between afternoon #napping and #cognitive function in the ageing Chinese population

Background Several studies have shown that afternoon napping promotes cognitive function in the elderly; on the other hand, some studies have shown opposite results. This current study further examined the relationship between afternoon napping and cognitive function in the ageing Chinese population. Methods A total of 2214 elderly were included (napping group: n=1534; non-napping group: n=680). They all received cognitive evaluations by the Beijing version … Continue reading Relationship between afternoon #napping and #cognitive function in the ageing Chinese population

The effects of #alcohol and #cannabis use on the cortical thickness of #cognitive control and salience brain networks in emerging adulthood: a cotwin control study

Background Impairments in inhibitory control and its underlying brain networks (control/salience areas) are associated with substance misuse. Research often assumes a causal substance exposure effect on brain structure. This assumption remains largely untested and other factors (e.g., familial risk) may confound exposure effects. We leveraged a genetically-informative sample of 24-year-old twins and a quasi-experimental cotwin control design to separate alcohol or cannabis exposure effects during … Continue reading The effects of #alcohol and #cannabis use on the cortical thickness of #cognitive control and salience brain networks in emerging adulthood: a cotwin control study

Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study

To determine if accelerometer measured sedentary behavior (SED), light‐intensity physical activity (LPA), and moderate‐to‐vigorous–intensity physical activity (MVPA) in midlife is prospectively associated with cognitive function. Participants were 1970 adults enrolled in the CARDIA (Coronary Artery Risk Development in Young Adults) study who wore an accelerometer in 2005 to 2006 (ages 38–50 years) and had cognitive function assessments completed 5 and/or 10 years later. SED, LPA, … Continue reading Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study

Mild to moderate partial #sleep deprivation is associated with increased #impulsivity and decreased positive affect in young adults

The effects of mild–moderate partial sleep deprivation on affective and cognitive functioning were evaluated in a naturalistic home environment, mimicking short sleep typically caused by demands from work or society. A total of 52 healthy individuals aged 18–35 was included in an 11-day study protocol. Participants slept at home, and sleep patterns were observed using actigraphs and sleep diaries. After maintaining habitual sleep for 7 … Continue reading Mild to moderate partial #sleep deprivation is associated with increased #impulsivity and decreased positive affect in young adults

Association of Low to Moderate #Alcohol Drinking With #Cognitive Functions From Middle to Older Age Among US Adults

..The mean (SD) age of 19 887 participants was 61.8 (10.2) years, and the majority of the HRS participants were women (11 943 [60.1%]) and of white race/ethnicity (16 950 [85.2%]). Low to moderate drinking (<8 drinks per week for women and <15 drinks per week for men) was significantly associated with a consistently high cognitive function trajectory and a lower rate of cognitive decline. Compared with never … Continue reading Association of Low to Moderate #Alcohol Drinking With #Cognitive Functions From Middle to Older Age Among US Adults

The association between actor/partner #optimism and #cognitive functioning among older couples

Higher optimism has been linked with health, well‐being, and cognitive functioning. Spouses also play an important role on people’s health, especially in older adulthood.. ..Optimism was assessed at baseline (t1) and cognition was measured every two years with up to five repeated assessments of cognition data over the 8‐year follow‐up period (t1; t2; t3; t4; t5). Results Results from multi‐level dyadic data analyses showed small … Continue reading The association between actor/partner #optimism and #cognitive functioning among older couples

#cognitive performance in relation to #hydration status and water intake among older adults, NHANES 2011–2014

..we tested if calculated serum osmolarity (Sosm) and adequate intake (AI) of water among women (n = 1271) and men (n = 1235) ≥ 60 years old were associated with scores of immediate and delayed recall, verbal fluency, and attention/processing speed. Sosm was categorized as < 285 (hyperhydrated), 285–289, 290–294, 295–300, or > 300 (dehydrated) mmol/L. AI of water was defined as ≥ 2 L/day for women and ≥ 2.5 L/day for men. ..Women with Sosm between 285 and … Continue reading #cognitive performance in relation to #hydration status and water intake among older adults, NHANES 2011–2014

Alcohol Consumption and Risk of Dementia and Cognitive Decline Among Older Adults With or Without Mild Cognitive Impairment

Findings were consistent when stratified by sex, age, and APOE E4 genotype. Compared with drinking less than 1.0 drink per week, complete abstention (in participants without MCI) and the consumption of more than 14.0 drinks per week (in participants with MCI) were associated with lower Modified Mini-Mental State Examination scores (mean difference at follow-up compared with baseline, −0.46 point [95% CI, −0.87 to −0.04 point] … Continue reading Alcohol Consumption and Risk of Dementia and Cognitive Decline Among Older Adults With or Without Mild Cognitive Impairment
